Music Video With Two Film Formats - Digital Camcorder and Digitized Super 8
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. Both types had different compressor types, frame sizes, and frame rates.
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, but not digitized to HD. The original Super 8 footage was given to me as a Timecode 10-bit uncompressed 4:2:2 file Quicktime file. Native Dimensions were: 720x486. I’m not sure what the frames per second are.
I used the video converter Wondershare to convert this Super 8 footage (which was in a Quicktime format) into an H.264 file. When I chose “current frame rate” in Wondershare, it came up at 29.97 fps. But I converted into Final Cut at 23.98 fps, thinking it might look closer to the 18fps it was shot on. The recently converted Super 8 specifications in Final Cut are: Frame Size: 1920x1440, Data rate: 2.0 MB/sec, pixel aspect: square. I converted it into an HD 1920x1440 H.264 file using Wondershare.
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
Audio Settings are: AAC, Data Rate: 320 kps, Sample rate: 44.1 kHz.
I would like to know how to fix my music video so that it plays smoothly and there are no discrepancies between the two types of footage. I also am about to begin another music video similar to this one with both Canon XH-A1 1440x1080 footage and Super 8 in the sequence together the same way so I want to make sure that this video also plays professionally without any stutters. I am wondering the following:
1.) What should be sequence settings in Final Cut Pro be with both Canon XH-A1 and Super 8 footage in the sequence together?
2.) Does the Canon XH-A1 footage need to match the Super 8 footage in frame size, file type and pixel aspect? If so, what should both of the footage specifications be?
3.) When I try to convert my Super 8 footage using Wondershare to 1280x720 and drag it into the Final Cut Pro timeline, it appears as a little box in the viewer, about 50% the size it needs to be. The other Super 8 clips in the timeline that are 1920x1440 appear as the correct size and fill the whole viewer screen, but the 1280x720 Super 8 clips look smaller. Then the native 720x486 size looks really, really small. Why is this, and how can I enlarge my Super 8 images in the sequence so that they are the same size as the rest of my footage?
3.) Is it okay to convert my digitized Super 8 footage using Wondershare, into an H.264 file with the dimensions described above? (Frame size: 1920x1440, Pixel aspect: Square) Should it be something else? 1280x720, 720x480, etc?
4.) Will I have to downgrade my Canon XH-A1 footage into regular SD in order for it to cooperate with my Super 8 footage which was not transferred to HD in the telecine process?
5.) What kind of Quicktime conversion settings should I use to export the file? What should my compression type, frame rate, frame size and pixel aspect be?
Any advice is greatly appreciated. Thank you!
Also: The audio is a completely separate track from the video files. For the music video, I used Super 8 clips and digital camcorder clips of live performances and I worked hard to line the lyrics up with the song, but the audio file is taken from their album and is 44.1 kHz.
Also, my Canon XH-A1 camcorder footage is supposed to be 23.98 frames per second, but for some reason in this sequence it is coming up as 29.97. I don't know how my frame rate changed but I would really like to get it back to 23.98. My super 8 footage was always at 23.98 I think, because when I ran it through Wondershare again, and said "keep current frame rate" it appeared as 23.98.
