16:9, 18:9, 2.35:1, 4:3, 4:5, 9:16, have you seen these values or heard about these values during productions? What do they represent?

• Closed captions are embedded stream of data that is a transcription of the spoken elements of the project. It is commonly used in television broadcasting where the audiences have a difficult time with hearing. 
• Commonly used caption standard is CEA-708
• Keying the captions will be at the captions panel, not at the program or timeline sequence panel. 
• You have to manually adjust the caption by breaking one line into two if it is too long or else the text will be cut off and not display. 
• You can also adjust the handle on the caption box to control when the caption should appear or when it should end.
• Hitting the + button at the caption panel will add in another caption label.

• How to properly export captions upon output.
• When exporting media, under captions tab, there are 3 settings which you can choose. 
• Burn Captions into Video is to baked the caption into the video itself. Captions cannot be toggle on or off. 
• Create Sidecar File create a second file alongside the video file, containing the caption information. 
• Embed in Output File enable the captions to display as a separate caption track after dragging the exported file into the timeline. 
• There are a lot of variables to which settings you can choose for the captions especially when you choose different video formats.

• Learn about different export settings.
• Learn about the difference between HD and 4K settings.
• 10 to 12 Mbps is a a good Bitrate range for most HD videos.
• 4K videos usually require a higher Bitrate range depending on which cameras used. 
• Hit the button nearest to Preset to save a custom preset. 

• Learn to export videos at different frame rates.
• Changing the frame rate of the video often entails Premiere Pro to duplicate occasional frames or subtract occasional frames. The negative ramifications to this is that it can create a jitteriness in video.
• At Time Interpolation, Frame sampling simply means adding or subtracting frames depending if you are going for a higher or lower frame rate. 
• Frame Blending. It means ghosting frames together. The frames are overlapped together and semi-transparent to create a little bit of blend from frame to frame. 
• Optical Flow is the highest level for frame conversion, it will slow down the export process immensely as Premiere Pro will specially calculate and analyse every frames and pixels. Then it will create artificial frames between frames to compensate, not just subtract or adding frames. 

• Learn to export videos of different resolution in the same sequence. 
• Maximum Render is use to export the video files of different resolution to the highest quality possible. This function gives a higher quality of scaling the video resolution, Premiere Pro will run a higher algorithm when having to scale clips to a different size than their original resolution. 
• Maximum Render also helps when it comes to scaling the video resolution from higher resolution to lower resolution.

• Learn the functions of Effects tab under the Export window.
• You can add a Lumetri Look/LUT to the entire sequence when usually that effect is added clip by clip. 
• SDR Conform is used when working with SDR footages, when you need to conform to the normal standard dynamic range rather than high dynamic range. 
• Image Overlay is used when you want to add a watermark to the video. You can change the position/size/opacity of the watermark.
• Name Overlay is used to label the video version which is still just a rough cut before sending over to the client. The label will be burnt into the video export.
• Timecode Overlay is to burn a time stamp on the video export to measure how far into the video we are. You can also change the position/size/opacity of the timecode overlay.
• Time Tuner is use when you want to compress or expand time. If you are trying to slow something down in order to match your video target duration. Premiere Pro analyze the entire video and look for frames of less action and movement, change and compress or expand time of those frames differently than on frames where there is a lot of movements of pixels to ensure you notice the time compression or expansion as little as possible. 
• Video Limiter and Loudness Normalization are useful if you work in broadcast television and are under a time crunch, both are use to make sure the video meets typical legal standards for broadcast. 
• Publish is used when you want to publish your video to social media platform directly upon exporting.

• Learn how to add Metadata into video export.
• Same as Captions, you also have the options to Embed in Output File, Create Sidecar File, both options or none at all. Not all video format has all 4 options. Quicktime has all of these 4 options. 
• Source Metadata and Preservation Rules are about any metadata that are added to the source media. 
• You can also add markers with the metadata when you export the video. Just make sure Export Master Speech Track and Sequence Markers is tick. 

• When exporting video, you cannot use Premiere Pro, you also can only export 1 video at a time but using Media Encoder, this will enable to export multiple video sequences without having to lockdown Premiere Pro itself. 
• Select multiple sequences and just select export media, then click queue.  Media Encoder will open immediately.
• To start exporting multiple video sequences, you just have to hit the play button. 
• You can also create multiple exports of a different video format over at Media Encoder. Select the videos you want and just click on Add Output button. To change the format, click on the Format Preset dropdown button and pick the video format you want. To change the fame rate, go to the Preset dropdown button.
