Recording 10-bit with the GH5S: MP4 or Quicktime?

Brian_Siano — Thu, 23 Aug 2018 17:24:49 +0000

Pretty basic question. If I'm recording 10-bit video with my GH5s, I can do it as an MP4 or as a Quicktime. But is there an advantage or disadvantage to using either of these? How does HLG impact on this? Or is All-I video of better quality?

WinRewrap - Batch ReWrap MTS to MP4/MOV .

fatpig — Sun, 30 Sep 2012 17:42:50 +0000

Hello,

I wrote a little Tool called WinRewrap. It will Batch Process MTS Files to MP4/MOV and adjust References to the MTS accordingly in your XML File. It uses ffmbc. ( http://code.google.com/p/ffmbc/ ) I wrote it primarily for exchange between the new Sony Vegas Pro 12 and DaVinci Resolve. But it can be used for any Batch rewrapping task of MTS.

Of course, this is a very early version, so please let me know any problems that may occur. Note: Audio was converted to AAC in v0.1. Later version keeps the audio stream.

I hope you can use it as well as I can. Ideas, suggestions and Bug Reports, please post here.

regards

WinRewrap v 0.4

Changelog 0.4:

Added Cancel Option while ReWrapping
Added PCM and No Audio option

Changelog 0.3:

Added Option to Convert Audio to AAC
Added Check for 0-byte Files (returns error now)

========================================

Requirements:

ffmbc.exe (Release was tested with version 0.7.1 rc7) put it in the same folder as the WinRewrap exe.
Windows 7 / Vista Users may experience errors related to writing permissions.

Fix: Turn up your UAC to "always notify". if you turn it to not notifying, some applications are automatically denied access. like winrewrap.

to fix those, copy WinRewrap and ffmbc.exe to your Project Folder. (Tip: WinRewrap starts with its containing Folder under the Browse Dialog, If its your project Folder you can just click OK.)

========================================

Features:

support for rewrapping .MTS Files to .MP4 and .MOV using ffmbc.exe

this is essentially a frontend for ffmbc, designed for batch processing project folders containing multiple MTS Files and optionally an XML.

This enables project export from The New Sony Vegas Pro 12 to DaVinci Resolve, and can also be used for normal batch processing of entire Folders from GH2, etc.

It will automatically replace the MTS extensions to your new Container inside the XML, so you can automatically use it with the rewrapped files.

Known Issues:

Big Endian PCM Audio is not supported in Stream Copy Mode as of Version 0.4 (AF100) WinRewrap can, however convert to little Endian PCM Audio.

dentfilmz — Fri, 24 Feb 2017 15:18:56 +0000

I am shooting a feature film and I am trying to shoot in 24fps but I do not want to use avchd. My mp4 mode on the g6 doesn't have a 24 or 25 fps All I have is 30 and 60fps. Does anyone else know what I am talking about? Check out the image I have attached.

MP4 workflow. Mostly on Linux.

I have a Panasonic v770 Camcorder.

It ouputs mov/mp4 files.

With QT Pro on Windows I can Trim and save without encoding. I'm looking for a similar workflow on Linux(Ubuntu/Mint).

Some of the linux apps such as Openshot do have mov/mp4 output but restricted to 40 Mb/s.

SD and HD (720 and 1080) bitrates for download files

AKED — Wed, 27 Feb 2013 05:42:33 +0000

Hi I have a question I wiuldlike to get some advise: I produce instructional video since 25 years. First S-VHS, then MII, (source S-VHS, DV later MII) and now HD with first HVX200 and now with GH1, 2 and 3 cameras.

Now I wat to offer my products as download files in .mp4 format.

Now one has to try to find the oprimum bitrate setting, to keep the quality as good as possible for the customer and, on the other hand, keep the files as small as possible, to make the download shorter. I know both contradict each other. The smaller the worse quality etc.

Now what bitrate would you suggest for

SD 4:3 SD 16:9 HD 720 HD1980

Any input would be greatly appreciated.
