The music video I recently posted online is having issues with "hiccups" and "stuttering" during playback. I have my video posted on Vimeo, and each time I watch it there are between 2-4 stutters which all occur in different points of the footage each time.
If it is not simply from my internet connection, I suspect there is an issue with my footage or sequence settings. For this music video, I used two types of footage.
First type of footage: Digital footage shot on my Canon XH-A1 camcorder set in HD. This footage has the dimensions: Frame size: 1440x1080, 29.97 frames per second, HDV 1080i60, 16-bit integer, pixel aspect HD 1440x1080.
Second type of footage: Super 8 footage shot at 18fps, which was professionally digitized. I used the video converter Wondershare to convert the footage (which was in a Quicktime format) into an H.264 file. This footage has the dimensions of 23.98 frames per second, data rate: 2.0 MB/sec, pixel aspect: square.
I put them all together into a sequence with the sequence settings being: Frame size: 1440x1080, Aspect Ratio: HD (1440x1080) Anamorphic 16:9: Checked, Editing Timebase: 23.98 (Custom 23.976), Quicktime Video Settings: HDV 1080p24.
I exported the project using Quicktime conversion with the settings: Compression type: H.264, data restricted to: 5000 bytes, Frame Reordering: No, Frames rate: Custom (23.976) - Yet "24" is automatically selected as the key frame underneath and I can't change it. Frame size is HD 1280x720 16:9 (because Vimeo's compression settings recommend exporting a 1440x1080 video as a 1280x720). Deinterlacing: No
