25p or 50p

[George Glou]

Dear friends....I mostly edit weddings...but there is a bit of confusion concerning the camera operators on what frame rate they should record.
We deliver on usb stick, keep in mind that here most of the tv would not play 50p on a usb. I dont know if there is something wrong with my exports. Some latest tv would play them but most of them not.
So I export 25p and everything is ok.
For slow motion they record from the camera it self so the footage I get is already in slow motion, because in 25p I can not reduce speed because it looks BAD !!!
So what would you suggest concerning the frame rate? Should I tell them to continue record on 25p? Some records on 50p and then I export in 25p but I am not sure if we are loosing in quality.
Any advise ?
Thanks

record in 50p.... you can slow mo it the footage.
also u can convert the footage to 25p.

record in 50p.... you can slow mo it and u can convert it to 25p.

Without loosing quality or strange issues of the people in video that move or dance?

25p is 25 frames per second, 50p is 50 frames per second (twice the framerate) more frames per second just means a bigger file because it has more samples taken per second, not a higher quality.

50p is easily turned into 25p as you have been doing, by essentially just displaying every 2nd frame, or if it is played back at 25p without dropping every second frame you will get a 50% slow motion without actually having deal with the slow motion you have experienced with 25p. You are not loosing quality, just loosing half of the temporal samples.

The reason many TVs will not play back the 50p footage is that 50p is not an original PAL framerate and most TV will not handle it unless they are very new.

My recommendation, if storage space and ability to edit the files is not a factor, is to shoot at 50p because you have the ability to do slow motion with any footage then, instead of just planned shots, and with 50p, you can also use that as a source for 25i if you need to, without having to do away with the temporal motion in the interlaced fields.

Thank you both very much !!!

25p is 25 frames per second, 50p is 50 frames per second (twice the framerate) more frames per second just means a bigger file because it has more samples taken per second, not a higher quality.

Granted, if the camera is for the most part motionless and there isn't a lot of movement being captured, 25/30p would be fine. However, I consider motion a big part of the overall image quality. When using 25/30p vs 50/60p in motion shots, IMHO 50/60p produces better imagery. The more samples during moments of motion, the better the image. The motion would either be from the events captured by the camera or even the motion added to the scene from the camera movement.
You can always go to 25/30p or 25/50/59.94i from 50/60p.


You have discovered that there is no universal USB playback requirement. I will say though, newer sets will play high frame rates using H.265.
You may have to make two master files, one 50p and one 25p.

George. If delivering wedding video on a USB stick in PAL land I have never had a failure with 1280x720P.mp4 50p. Let the TV upscale to 1920x1080i.
Starting material can be 3840x2160 50p, 1920x1080 50p or 1280x720 50p. If your project settings at set up correctlty then Settings> project settings will allow you to switch freely should you so wish. I now start from 3840x2160 50p but mixed of FHD and HD can be added. So far not had to consider mixed framerates or i/p mixes. Not had to consider guest clips from 'phones.

I deliver 1080 50i on USB and have not had one reject (all TV support 50i but only some support 1080 50p) (all TV support 1280x720 50p)

But can you deliver a wedding in 1280x720 50p? I mean would that be nice as quality? Its a wedding...they pay you to deliver 720? I dont know... I will try to export one in 1280x720 to see if there is much difference...

1280x720 50p looks way better than any DVD, so they should be happy

the only issue is that some TVs don't play it full screen unless you change the display setting, usually done from the TV remote

Maybe output in HQX and then convert to .mp4 using Handbrake. In past posts I think Anton posted a .json template for this conversion, either way it's pretty easy. Octogenerian so memory possible slipping along with spelling.

Could you please tell me how to get an hour of hd on usb for playback on tv. Trying to workout how to overcome fat32 while preserving quality. thanks in advance.

[ulyssesvideo]

you can re format the usb stick to exFAT or NTFS to get around the 4gig file size
.... But you may have issues as the tv may not recognize the usb stick. give it a try and see.

[antonsvideo]

exFat is a no go for TV, NTFS should work on most

you can also use Fat32 and set Hanbdrake bitrate to 8000 and this should make a file of 3.8GB (8M quality in Handbrake is plenty good)
