How to Improve Recording Video and Audio Quality in oCam

How to Improve Video Recording Quality


By default, oCam uses the

MPEG-4 video codec.


The MPEG-4 codec, which is used by default, provides medium-level video quality by nature. However, it is set as the default because it is suitable for recording on low- to mid-spec computers, does not use a hardware encoder, and offers good software compatibility ( it can be played in most video players ).


If you have an NVIDIA graphics card ( GTX 600 series or later for desktops, or GTX 650M or later for laptops ) or if your CPU performance is high, you can improve video quality by recording with the NVENC H.264 encoder or the Open H.264 encoder.


As shown below, click the Codec button in the oCam main window and select either NVIDIA NVENC H.264 ( your graphics card must support it, and if it does not, an error will occur and recording will fail when you start recording ) or the Open H.264 codec to record.


For the Open H.264 codec, you need to set Recording - General - Quality to Very High in the settings to get the best video quality, as shown below. ( In the case of the NVIDIA NVENC H.264 codec, the settings below do not apply. You can change its settings from Codec - Hardware Encoder Settings in the oCam main window. )





* In the case of the Open H.264 codec, setting the quality to Very High provides good video quality, but it uses a lot of CPU resources, so frame rates may drop significantly when recording games. If your system performance is not sufficient, we recommend using the MPEG-4 codec.


* In the case of the NVIDIA NVENC codec, because it is a hardware encoder, it causes almost no frame drops during game recording and offers the best recording performance among all built-in codecs in oCam. If your graphics card supports it, using the NVENC codec is the best option.


* When using the NVIDIA NVENC codec, some games use a large amount of GPU memory, and encoding also uses a large amount of GPU memory, so recording may fail if GPU memory is insufficient.


 * The MP4 container was used in the example above, but it can also be used with MKV, M4A, MOV, and AVI containers.


 

How to Improve Audio Quality


By default, oCam uses the

AAC audio codec ( 192 kbps ).

To change the sample rate or bitrate of the audio codec, click the Codec button in the oCam main window, then click Audio Codec Settings.


Then the following window will appear.


 

As shown in the image above, the supported audio codecs are AAC, MP3, MP2, WMA, and Flac.


Personally, I recommend using the AAC codec because it is the most widely used and offers the best compatibility.

You can improve audio quality by changing the bitrate or sample rate.

For the AAC codec, the maximum supported bitrate is 512 kbps, and the maximum sample rate is 96000 kHz.


If you want to record losslessly, you can use the Flac codec, but the recording file size may become large.


To change the audio codec you want to use for recording, click the Codec button in oCam, select the container you want ( for example, assuming you are using MKV ), and then select a codec in that container that includes the audio codec you want before recording.

oCam Advanced Settings - Save

Click Tools - Options on the oCam main menu to view the settings in the Save category.



 


By default, the save path is set to the "This PC-Documents-oCam" folder in Windows 10, and all recordings, audio recordings, and captures are saved to this location.


The save path can be changed by clicking the button.

 

The file name to be saved follows a predefined format or a user-defined format, and by default it is set to "<Prefix>_<YYYY_MM_DD_HH_NN_SS_Z>".


The file name format can also be changed by clicking the button, and when you click it, you can see the predefined formats.



If you click the Help menu item, you can see more detailed information about the format, as shown below.


( When the Help menu item was clicked at 11:29:49.902 AM on June 16, 2016 )

<Y> = 16

<YY> = 16

<YYYY> = 2016

<M> = 6

<MM> = 06

<MMM> = 6

<MMMM> = June

<D> = 16

<DD> = 16

<DDD> = Thu

<DDDD> = Thursday

<DDDDD> = 2016-06-16

<DDDDDD> = Thursday, June 16, 2016

<T> = 11:29 AM

<TT> = 11:29:49 AM

<AM/PM> = AM

<a/p> = a

<ampm> = AM

<#> = 1

The file name format may feel difficult for some users, so here are a few examples.


- If the file name is <Prefix>_<#>, then <Prefix> is the prefix and # is the serial number.

The prefix is replaced with Recording when recording video, Audio when recording sound, and Capture when capturing the screen, while # is replaced with a serial number.


For example, when you finish recording the screen, a file named Recording_1 is created. ( Only if there is no similar file name in the oCam save folder. )

And when you record again, a file named Recording_2 is created. The reason the serial number becomes 2 is because a file named Recording_1 already exists.


- If the file name is <ProgramName>_<#>, then <ProgramName> represents the name of the program being recorded. In normal screen recording, it is replaced with oCam, and <#> is added as a serial number just as before.


However, when recording a game, recording starts inside the game program, so the file is created using the name of the game's executable file.


- If the file name is <dddddd>_<#>, then dddddd means the localized date, so on a Korean operating system it is replaced with the current date at the time this was written, Thursday, June 16, 2016, and # is filled in with a serial number.


The localized date varies depending on the language settings of the operating system. In other words, it appears differently on an English OS because it uses the format built into the operating system.


- If the file name is My_<#>_th_<Prefix>_File, then when recording, a file named My_1st_Recording_File is created, and when recording again, the file name becomes My_2nd_Recording_File.


- If the file name is <UserID> recorded <Prefix> of the game called <ProgramName> on <DDDDDD>. then it may be created as "AdvancedDeveloper recorded Recording of the game called LocalDeformablePRT on Thursday, June 16, 2016." The content inside <> varies depending on what is being recorded.


Serial number start means the starting number of the serial number that can be set with # inside <>.
