3 Different Camera Sources, 3 Different Frame Rates, Data Rates, Etc.

Report · Jan 20, 2017

I am editing a video. Apparently the footage I was given uses 3 different cameras. I'm wanting all the footage to flow seamlessly without it being too noticeable that there 3 different camera sources used. However at the moment, when exporting the footage, it is very noticeable.

Here are the specs of each source of film:

Source 1

-Frame Width -> 1920

-Frame Height -> 1088 (not 1080)

-Data Rate -> 46158 kbps

-Total Bitrate -> 47694 kbps

-Frame Rate -> 23 frames/second

Source 2

-Frame Width -> 1280

-Frame Height -> 720

-Data Rate -> 9174 kbps

-Total Bitrate -> 9299 kbps

-Frame Rate -> 29 frames/second

Source 3

-Frame Width -> 1920

-Frame Height -> 1080

-Data Rate -> 20120 kbps

-Total Bitrate -> 20217 kbps

-Frame Rate -> 20 frames/second

I am using Adobe CS5.5 to edit. I have done all of the general sequencing and editing I want, minus whatever I can do to make the appearance of the videos match more closely.

What suggestions do you have to make all the footage appear as seamless as possible when exporting the video?

Hi 3Strykes:

If there was an award for most non-standard frame rates in a PR project, you'd be in the running to win it.

Quick question: does the picture form each camera not match to due the temporal quality or due to the visual quality?

I'm trying to remember when After Effects gained the "Timewarp" effect (it might be in CS5.5, but it might not). With where you're at, I'd send everything to After Effects and apply Timewarp at 100% speed (assuming you have access to Timewarp). That should give you the cleanest frame rate remastering. Of course, you'll have to pick one frame rate to conform to in the first place. I'd opt for 23.976.

If you were to upgrade to CC 2015 or newer, you could use PR's new Optical Flow instead.

To answer your quick question, I'd say honestly a combo of both. The 2nd and 3rd sources are the least quality of the 3. The 2nd source was an interior shot without proper lighting equipment - shot with a handheld digital camera. The 3rd source was done outside on Christmas day in the winter (overcast) with a mobile phone, while the 1st source was done in the summer outside with much better natural light with a DSLR.

For the record, I'm just editing, wasn't involved with the shooting. But I've learned a lesson in ensuring that camera people are prompt, professional, and don't flake on shooting, otherwise you end up in an emergency situation where using your cell phone is the only option lol.

After Effects does have Timewarp! So I'll have to learn more about all it can do. Should I export from Premiere first and import all the clips as one file? Or import the Premiere project file into Timewarp? Or do each source video individually?
