View Full Version : QT Player7 Can scrub video frame by frame, Do other video players support this?

Quicktime Player 7 on Windows supports being able to scrub frame by frame through any h.264 encoded video, including being able to accurately scrub backwards frame by frame, even if the previous frame was not a P frame.

MPC-HC has frame by frame control, but does not allow you to scrub accurately in h.264 video. Is there another media player that supports proper color space conversion, pixel aspect ratios, and can scrub through h.264 video like QT7 player can?

The reason why I'm asking is that we're trying to get a more modern video format for our animators to review footage frame by frame, without having to resort to a large image sequence or uncompressed video format, so I'm open to other formats that other post-production houses can export. Pay codecs are most likely out of the option unless we can buy one license for an entire company. Color accuracy does matter for some people, and we've found that the Quicktime container it self has audio sync issues in certain instances, so we don't want to use anything inside a Quicktime container.

Just a slightly off-topic question:
When I went trough mastering processes, I just played back the raw, lossless images. I was very glad this was possible, as converting terabytes of source images to encoded, DC, HD and two SD video formats took me a several days to encode (without supervision, just a dedicated computer running a script). Having to do that multiple times would really be the last thing I ever wanted to do. Also, I would be uncomfortable if I would have to limit the source (XYZ) colorspace to bt.709/bt.601 and sacrifice the lossless for lossy for a quality review of the master. Do you have a problem with local storage capacity, portability or something else that you're willing to take the time and effort of encoding the source material multiple times during mastering?

Our work ends up getting displayed back in real time in a video game, so we don't need to see an uncompressed master. Ultimately our director approves what runs in the game, but our animators need the video clips to review several shots quickly rather than trying to trigger them to play in game.

Also, we have hundreds of artists that work for us, We don't have the budget to buy a DAS for every artist that can support 720P uncompressed at 30FPS.

I'm still looking for a media player/decoder that can move through individual frames forwards and backwards on a video file that isn't in a quicktime container. No software has this kind of functionality?

Loading the file in an avisynth script (with ffms2 preferably) and use mpc-hc to play the .avs file.

a. maybe look at the html5 video and javascript stuff around it (http://www.massive-interactive.nl/html5_video/smpte_test_universal.html)
b. or easier, use safari and link directly to mp4 files (the default html5 player which is probably qt based has a frame seeking controls already on the place)
c. or maybe at adobe strobe component, which seems to have a really 'cool' seeking support, but i don't know if can be frame seekable.

easy to complex would be : b < a < c
