An audio pull up or pull down is needed when there is a frame rate chenge on the picture that affects its lenght. The pull up/down can be done in two steps: lenght change first, then pitch correction or ir can be done in a single step. Time/Pitch Shift is a complicated process that can produce artefacts, metallic timbres and phase issues.

The most common practice is stretching the audio. Making it longer, and pitching it up again. Using pull, you can actually “pull” your audio session, so it runs for 31,250 seconds, thereby eliminating the stretch-process. (You are actually faking that your session runs at slightly lower sampling frequency than 48kHz)

If you have 25 fr PAL audio, you would generally do a 4% pull DOWN, not Up, assuming you have a 25 fr PAL Film transfer Master. From that point, you should run PT with a .1% Pull DOWN on to run at 23.98 (NTSC) speed. so your total pull down is 4.1%.

Pull-up and Pull-down Resistors - Circuit Basics
https://www.circuitbasics.com/pull-up-and-pull-down-resistors/
When the button is not pressed, the input pin is pulled high. The value of the pull-up resistor controls the voltage on the input pin. When the switch is open and a high pull-up resistance value is combined with a large leakage current from the input pin, the input voltage can become insufficient. This is called having a weak pull-up. The pull-up resistor’s actual value …

From the 'Source Sample Rate' drop-down menu choose 48 kHz (Pull Up/Down) and then 47, 952 - 0.1% Down (Film to NTSC) Choosing the appropriate source sample rate Pro Tools will then treat the audio as if the destination sample rate of the session is 47952 Hz; if that was the case then 48000 samples would take slightly longer than 1 second to play back and …

The best is removing the original pull-up or pull-down. If not and if you have enough space, you can add another resistor. There is a rule that the new pulls should be at least 15 time the original pulls. That say, if your pull-up is 15K, then if you want to add another resistor to change it to pull-down, your resistor value should be 1K or so.

Pull-up and Pull-down Resistor Values. The appropriate value for the pull-up (or pull-down) resistor is limited by two factors. The first factor is power dissipation. If the resistance value is too low, a high current will flow through the pull-up resistor, heating the device and using up an unnecessary amount of power when the switch is closed.

The resistance value for a pull-up resistor is not usually that critical but must maintain the input pin voltage above V IH. The use of 10kΩ pull-up resistors are common but values can range from 1k to 100k ohms. Pull-down resistors are a little more critical because of the low input voltage level, V IL(max) and the higher I IL current. The use of 100Ω pull-down …
