Editing with 10fps transcoded VHS tape

New Here ,
Aug 27, 2017 Aug 27, 2017

Hello everyone,

I've never had to edit with such fps, and when I pull my rushes in my sequence and select change sequence settings, the rushes playback super choppy eventhough they are fps and the timeline is fps.

Image Size: 768 x 576

Frame Rate: 10.00

Source Audio Format: 44100 Hz - 16 bit - Mono

Project Audio Format: 44100 Hz - 32 bit floating point - Mono

Total Duration: 01;38;50;00

Pixel Aspect Ratio: 1.0

Here are the exact rushes info premiere pro is showing: I thought rendering would do the trick but it didn't. I also tried importing the rushes into a 25fps sequence and that didn't work either, still choppy. Any idea?

Thanks in advance for your help!

T

was that the native recording fps? I've never heard of a 10fps vhs. can you get the original master and import with bm shuttle and vhs player? should be 29.97fps of some sort.  10fps is pretty much wasting your time as there is not enough interpolation data. even set as optical flow pixel motion in export from a 24fps sequence.

Hello Chris,

Thank you for your reply! What exactly is bm shuttle and how do I use it to import the original master? I'm not sure how to check what the original frame rate is outside of premiere pro.

I tried to make a sequence at 29.97 and drag footage onto there but it didn't work, (I know that's not what you recommended but tried anyway).

Best,

T

it's the Blackmagic Design Intensity Shuttle for USB 3.0

-VHS capturing for editing instructions:

1. short answer, buy a panasonic 4 head vhs that outputs component and Blackmagic Design Intensity shuttle/Pro 4k(support capture and playback output and its mjpeg codec)

2. long answer(for when you have free time to read below)

2 words: compression and resizing.

Tip #1. Many capture cards, have a native resolution size and then they just resize to whatever you request. If you have a fast computer, try to capture

their native, even if its way bigger than you need. You can then resize with professional software/hardware later on.

If you have space issues, capture 29.97fps  640x480 or 720x480 29.97fps. but I'd go with 720 so that you have a standard scalable resolution. Don't capture with contrast filters on! AE can do better unsharping/contrast in post.

if the software allows it, try 720x486. There's 486 visible lines sometimes in the source footage. Think "the ring".

a digital NTSC video frame is 720 pixels x 486 lines, and a PAL video frame is 720 pixels x 576 lines.

other technical considerations for ntsc:

color management: BT.601 16-235 or 0-255 full gamut(test). (don't use 1953 color)

White point is D65 6500k. Top/even field.

0.91 pixel aspect ratio

gamma 2.2

Tip #2.Capture at little to no compression so you can recompress later. It's called generation loss. The more you compress, the more blockiness/artifacts appear. Some of the best capture cards actually can be set to many pixel sizes and you can choose the codec of your choice depending on your hard drive speed.

picvideo codec; it's perfect for 7200rpm hard drives. supports

Advanced Deblocking of Highly Compressed Video, DirectShow Codec.

https://www.accusoft.com/products/picvideo-m-jpeg-codec/pricing/

Some newer models: all component, not composite:

Blackmagic Design Intensity Pro 4k ProRes and DNxHD, or as fully uncompressed 10-bit video,

Black magic decklink can capture uncompressed, for instance. but it needs special usb renises driver

Diamond Multimedia USB 2.0 High Definition can capture component.

StarTech.com Standalone Video Capture component.

Matrox MXO2 Mini High Definition HDMI and Analog I/O Device component

Hauppauge Colossus PCI Express Internal HD-PVR With Component

Tip #3. You'll want a 4 head S-VHS with component output and Time base correction to reduce fringing and poor color. If you can find one used in TV stations, they are professional quality. Clean with alcohal on the heads, run dummy tape cleaner. You'll want to stay away from composite. It is an old, noisy way to combine all singals. s-video is a little better. Use component intead, as it is the best.

Tipe #4

If you have a slow computer and little disk space, Picvideo codecs(a motion jpeg) always worked well for me because its intraframe-only compression is easy on computers, hd space and cpu's. Prores/DNxHD is also small.

Tip #5

codec capture roundup:motion jpeg's, h.264

advantage mjpeg:

mjpeg tolerates rapidly changing motion in the video stream, whereas compression schemes using interframe compression can often experience.

disadvantage h.264:

cpu lag, interframe compression can often experience unacceptable quality loss when the video content changes significantly between each frame. temporal compression can create "artifacts" or remnants of previous R-Frames, until the next I-Frame refreshes the scene

advantage h.264:

smaller file size than mjpeg

advantage ProRes:

compatible mac, small size, less compression

fully uncompressed:

if your raid can handle it, go for it! nothing beats 100% perfect quality uncompressed.

Tip #6 Output or final render gear:

output: Blackmagic Design Intensity Pro 4k-realtime playback output

other stuff:

supports color management BT.601.hardware Algolith box, terrenax box, topaz enhance,After Effects preserve upscale, DCT artifact removal, resize, flicker, mosquito noise, color halos, deinterlacing, etc.

----------

Tip #7 Deinterlace with the highest quality deinterlacer before final render/upscale or you wasted ALL previous steps!
