(I thought I had commented here but I don't see it. Apologies for any dupe). Thanks, that looks promising. We'll have a chance to test it in the week ahead.

comment Does raising the framerate while not changing the bitrate result in quality loss?
@Gin-San - My 'if' was to cover the case where you encode 50i vs 25p, for example. It might have been clearer to just say that whenever the pixel rate increases, you get lower quality from the same bit rate. As the Professor points out, the relationship isn't linear -- modern codecs deal well with the case where added frames are substantially similar.

Not quite. The input stream is a constant frame rate, but the arrival times may vary because of the path it takes. Think of it as having jitter and drift. This device or software would simply delay some frames more than others. It's a FIFO with separate input and output clocks: the input is clocked by the arrival of new frames, the output is clocked at a fixed rate. The goal is to have a known delay between the original CFR stream and the output CFR stream, that absorbs any path jitter.

comment Can I use any audio recorder for filming?
The answer to the question "Can I..." is "Yes." But without knowing what you expect or why you're asking, there's no way to know if your results will be satisfactory.

comment Millisecond stopwatch for visual stereo video synchronization measurement
@Kozuch - One camera or two, the frames occur at 16ms intervals (assuming 60fps). It makes no difference if the cameras are taking at different times: if you observe, side-by side, still frames from the two cameras, you will always see the images as captured at their respective times. Any time difference you see on the display can't be affected in any way by the display's speed or refresh rate. In any case, AJ has given you a good suggestion to use audio rather than video to determine the offset.

A faster display won't change anything. All that matters is the frame rate of the camera. Your captured motion is quantized at that rate, and observing the quanta more quickly or more often doesn't make those quanta any different.

comment Are there any video programs to trim and export multiple videos at once?
Is 'all at once' a firm requirement, or would it suffice to submit all the videos in a batch to be processed serially with no further action needed? Also, what form are these videos in -- what codec, etc?
