Vimeo stop-action single-frame advance holding SHIFT & arrow keys

[Chas Tennis]

Just learned that Vimeo has a stop-action single-frame capability using the arrow keys.

When watching a Vimeo video on line you can do stop-action single-frame, forward and backward, using the arrow keys.

Hold SHIFT KEY and use the RIGHT & LEFT arrows.

Often, however, when first hitting an arrow key it may skip to the next video in the account. This may be a new Vimeo capability....?

Nice feature, just tested and it does work.

Vimeo launched a new player earlier this month and probably did include that feature with it...

New Vimeo player

THANK YOU Chas, this is amazing. Really helps analyzing video

Chas, some questions for you:


1. can you do this stop action single frame feature on Youtube?
2. Have you figured out how to do the stop action single frame on an iphone 5s? I got a 5s yesterday and am wondering if you had any info... I know you've asked before and didnt get a response. This would be really cool to find out though, so I will inform if I find out anything. I'm going to call Apple
3. Can Vimeo handle high speed video? That is, if I were to upload a 120 FPS video on Vimeo would it compress it back down to 30 FPS like youtube?

1) Single Frame Advance on Youtube. As far as I know some Youtubes seem to do single frame based on the arrow keys but not the majority. Most YT videos skip many frames with the arrow keys. I just tried holding the SHIFT key for a YT (just in case the new Vimeo capability somehow also would apply to YT) but YT skipped a few frames forward as it most often does. Pressing the play-pause button as fast as possible is the only work around that I know of for YT. With a number of attempts you can usually stop on the frame that you want.

Variable Speed Playback on Youtube. Youtube does have a special feature where you can play back a normal 30 fps video in slow motion or fast motion, several speeds from 25% to 4X etc. . You have to select a YT option, 'HTML5', to do it. You then can click the 'gear' icon on each YT video - try it to see if you already have it.

2) Single Frame Advance on the iPhones. I did finally get one answer. I thought it might have been on here. A response indicated that there is an application for an iPhone probably the 5s?? that allows single frame advance maybe backward also.

3) Vimeo Playback Video Frame Rates and Original Video Recording Frame Rates. My high speed camera, a Casio FH100, records at high speed, such as 240 fps, and processes that video into a standard 30 fps video file. When played the video shows motion at 1/8 speed of the real motion when recording was at 240 fps. My Canon Powershot does the same thing. See my Vimeo videos. I assume that most other HSV cameras are the same.

However, I uploaded a 60p fps video from an Aiptek camera and Vimeo reduced it to a 30 fps video by discarding every other frame.

I don't know what will happen with the iPhone 120 fps but I assume it is not difficult since I have seen iPhone 5s videos on Youtube.

iPhone 5s golf swing Youtube with little motion blur or Jello Effect distortion.

Also Search: Vimeo iPhone 5s 120 fps

Editing High Speed Video Recordings. Another capability that is very important for high speed video is editing - especially to get rid of all the dead time that HSV produces. I don't know how that works on an iPhone 5s. I hope that you will post some information on iPhone 5s editing. That low cost Canon Powershot 110 HS that I tested and recommended edits very fast.

Jello Effect Distortions. You should also evaluate the Jello Effect distortion on the iPhone 5s. The Jello Effect distortion looks small based on the golfwrx site YT video above. For example, JE distortion falsely bends golf clubs and has fooled many golfers for years. There are some JE tests in my Vimeo videos.

In addition, Youtube and Vimeo (free version) 'compress' the video file into a smaller video file before storage. This compression reduces video file size by saving a reference video frame and than only saving the difference between the reference frame and the frames being compressed. Smaller video files result with possibly some loss of video accuracy.

Thanks for the reply. I was able to find the app very easily and look forward to use it to analyze high speed video.

I will get some test vids up soon for you to see. And with regards to the HSV, the iphone 5s apparently shoots 120 fps and plays it back at 30 fps, similar to what your camera does

I will search the videos you posted on the 5s so I can make the most out of this phone for tennis purposes. I don't know about the jello effect, but I will research it now. Hopefully it won't be too bad on this phone

Again thanks, you've really helped me out, especially with this app

Chas, are there any other settings to manually change to help reduce motion blur in cameras without manual shutter control? ISO, white balance, etc?

Also I was wondering... has your HS/HD video selector switch on your FH100 as ever stopped working?

I went to use mine recently and it is stuck in HD mode suddenly. Switching to HS doesn't change anything, just films in HD only now. Casio support said do a manual reset but that didn't work so I might have to take it to a service center. Everything else works perfectly though...

Online research just showed one person with similar problem when camera was new and they sent it in for exchange, (dpreview from 2010). Just hoping you might have magic fix! I am looking at ZR400 and Powershot HS110 too though but I like that manual control on the FH100 of course!

I believe that when cameras are in automatic exposure control (AEC) for high speed video that you cannot always control the shutter speed and produce videos that are not too dark. I never use it so I could be wrong. Let's say that you use automatic exposure control "Shutter priority" mode, if offered, for high speed video mode. I believe few or no cameras offer shutter priority in high speed video mode but I can't guarantee that. If the camera's AEC is programmed to never use an ISO above 400 and the light is not strong then you will get a very dark or unusable video. If manual exposure control you can set ISO to 1600 or 3200 and get a bright video. Most cameras have fully automatic exposure control in high speed video and don't offer shutter priority mode for high speed video. What ISO will they use? Some cameras with automatic exposure control might allow ISO to be manually set but you would have to determine that because I don't know and it is important. I can't control the ISO in the Canon Powershot 110 HS for high speed video.

My Casio FH100 in MANUAL has to have the ISO also set manually (not left on "AUTO"). Otherwise, it will produce a much darker video than it can get with a higher ISO. I guess ISO Auto is limited to a low ISO.

Discussion of automatic exposure controls especially shutter priority mode.
http://www.kinovea.org/en/forum/viewtopic.php?pid=2835#p2835

Some recent DSLR's offer manual exposure control and very fast shutters at 60p fps.

I have never had the HD/HS switch fail to work. I have never used the camera reset but I believe that is has a factory reset - check the user's manual. It might lose the video label count. Before taking it back for repairs I'd look into the reset function if it has one.

Did you try removing the battery for a while?

The only problems that I have with my FH100 is that the date is now usually lost when the battery is changed. I have to reset it almost every time I change the battery time. I have seen posts on that problem.

The FH100 is a much higher performance camera for high speed video with minimal motion blur. It's also excellent for high speed video using the telephoto lens and still getting a fast shutter even with artificial light levels.

See the Kinovea comments on the ZR100, 200, and 1000. You will get more motion blur except perhaps in bright sunlight. Also, the fastest shutter speed is not nearly as fast.

your mechanical SD/HD switch is perhaps misaligned. It is essentially a lever, and if the pin (inside the case) popped out of the groove, moving the lever on the outside does not move the lever inside the camera. If that is the case you may be better off NOT to move that lever until it gets fixed. Or you are risking breaking it. (That's just a thought, but most likely since the electronics rarely go bad. It is almost always a mechanical failure.)

As far as date resetting when removing a battery. Inside the camera there's another small battery (like watch type one CRxxx). It is likely dead now and that's why when the main battery is removed the clock gets reset. It is actually quite a pain to open the case and replace it yourself, so you may just need to live with it, not a big deal after all. Hopefully that battery won't leak...

I started searching the internet for the internal battery and did find some replies for an internal battery for other Casio models. None yet for the FH100.

However, I just checked the User's Manual and found this special reset instruction under 'Trouble Shooting'.

The time and date
settings configured
the first time after
purchasing the
camera are reset to
their factory
defaults when I
remove the
camera’s battery.

Load the camera’s battery and reconfigure the time and date
settings (page 19). Do not remove the battery from the camera
for at least 24 hours after configuring time and date settings.
After that, the settings will not be reset if you remove the
battery.
• If the time and date are reset to their factory default settings
when you remove the battery after it has been loaded for
more than 24 hours, it could mean that the camera’s setting
memory is defective. Contact your retailer or a CASIO
authorized service center.

I'd assume that I have done the 24 hour wait in the normal use of the camera but will try again soon and update.

Ah, thanks. I sort of envisioned it that way too and was even tempted to open up the case to see if I could do anything...luckily I didn't! No spare jewlers tools lying around... yeah, the date thing is annoying - I just go right to set time w/o putting in the info, not too much a hassle.




Chas - I just noticed the Vimeo frame advance doesn't work on my Firefox browser but works on my Chrome browser. Haven't tried IE yet. Which browser did you use or have you tried other ones?

I have seen a internet site that breaks down electronics disassemble the Casio FH100. Might have been a Youtube but I don't think so.

I'm using Firefox and the SHIFT + ARROW KEYS work for me. I have Windows 7 and a HP laptop 2 years old. Does it depend on your internet speed?

My Samsung phone plays Vimeo videos for the first time but I don't see how to do single frame on it.

I've disassembled fh100 myself, so I know for a fact there's an internal battery in there. I can't say for sure that is what would keep the date correct - but what else would it be used for? It's not really customer replaceable part so perhaps that's why it's hard to find any info on it? (I may have taken some photos while it was disassembled, if I find it I'll post it here)
edit: here is the photo (from this site: http://www.chipworks.com/en/technical-competitive-analysis/resources/blog/teardown-of-the-casio-exilim-ex-fh100-digital-camera/)

you can see the battery in the lower left part of the pic.

 

[Chas Tennis]

Thanks a lot. That makes sense. I had found the Chipworks picture but could not find the battery. Some other replies about replacing batteries of other Casio models referred to soldering the batteries in, does that seem correct? Makes me question the rationale for putting the battery permanently in the camera in a way that it cannot be replaced by the user.

For now, I'll put in the dates after each battery change and hope that is the end of it.
